Unlike conventional waste traps, HepvO does not rely on trapped water to create a seal.

Water seals are prone to failure by Evaporation, Siphonage and other Mechanisms.

HepVo uses a self sealing membrane which performs the same function as a water seal trap

No risk of depletion or freezing.

Actively eliminates negative pressure within the waste system

No secondary venting of the waste system is required

HepvO valve can be installed vertically or horizontally (with an adaptor)

This enables valuable space-saving opportunities to be achieved.

Great for RV's in storage for weeks or months

No need to winterize Hepvo with antifreeze

Will not hear flow, bubbles, groans and other noises from your pipes

Pipe Size: 1 1/4"

Hepvo Hygienic Self Sealing Waste Valve - 1 1/4"

Installation Steps:

Cut the tube to length, allowing for the full compression socket depth, (preferably using an appropriate tube cutter).

If using plastic tube remove any loose material from the end. If using metallic tube remove any ‘burr’, and file if necessary to remove any external sharp edges. Mark the socket depth on the tube, and check that the tube section to be joined is free of any surface damage which may affect the joint seal.

Unscrew the cap from the outlet/inlet adaptor and slide the cap and rubber seal onto the tube.

Insert the tube end fully into the socket.

Slide the rubber seal and screwed cap up against the face of the socket, and tighten the cap by hand, (check that the cap is square to the body and does not ‘cross-thread’), hand tight should be adequate to form a proper seal.

Threaded connections can be made to the inlet or outlet of the valve. At the outlet it is first necessary to remove the cap and rubber seal. If making connections to threaded components that do not have an integral seal (for example connection to DWV adaptors) PTFE/TEFLON tape should be applied to the thread prior to assembly.
